架构行为

目的与范围

用途与范围

本单元定义当前内存代理以及显式选择的 PE 的标量 GPR 读写行为。

概念与架构状态

当前代理与每 PE 访问

ReadGPR 和 WriteGPR 使用 _CurrentMemoryAgent 委托给 ReadPEGPR 和 WritePEGPR。每 PE 辅助函数同时用选定的内存代理标识和 GPR 索引访问 _PEGPRs。

规则与交互

零寄存器行为

每个 PE 的 GPR 索引 0 都读作 Zeros{PTO_XLEN}。写索引 0 不产生状态效果。

对于每个非零索引，读取返回所选 _PEGPRs 条目，写入则用给定 Word 替换同一条目。

边界与未定义范围

架构边界

当前代理包装函数不会把一次写入广播到多个 PE。它们只选择 _CurrentMemoryAgent；显式跨 PE 检查或更新需要使用每 PE 辅助函数。

使用示例

示例性别名示例

假设当前内存代理是 PE1。用 WriteGPR 向非零索引写值，会改变 PE1 对应的 _PEGPRs 元素；通过 ReadPEGPR 读取 PE0 的同一索引则是另一次状态查找。
